Updates password matching regex in ServerSpec tests

We've been incrementally refining the regex that matches the
automatically generated passwords and secrets used for auth between the
service components. Haven't see a definitive declaration of allowed
characters there, so adding narrow exceptions when tests fail with
known-working combinations generated by the jitsi setup scripts.
